    Abstract: This article studies the ways that the performance of direct drive (DD) serial robots changes as system size is changed. We are particularly interested in the physical laws for scaling down direct drive arms to small sizes. Using theoretical scaling analysis, we show that there is a net physical performance advantage to small direct drive arms. A key factor for direct drive robot performance is the torque-to-mass ratio of the actuators, U. We show how U varies with the scale of DD actuators, and we also calculate how the dynamic performance varies with scale and U. We compare our calculations with experimental measurements of actuators of various sizes taken from small hard disk drives and compare them with published data for larger motors. Finally, we describe a prototype, five- axis, direct drive serial arm having a reach of 10 cm and a work volume of about 136 cm 3 . Some potential applications are briefly discussed.

    When Can Negativity Mean Success? Gender Composition, Negative Relationships and Team Performance

    Abstract: Teams are often plagued by internal discord, such as negative relationships, which can impede successful team performance. While most teams eventually encounter negative relationships, we have limited knowledge on how teams manage this negativity. In this article, we expand scholarship on teams by exploring an inherent team characteristic, gender composition, to assess its role in how teams cope with negative relationships. On the one hand, social role theory suggests that teams comprised of more women will perform better in the presence of negative relationships. On the other hand, theories and evidence on personality and individual differences suggest that teams comprised of more men will perform better in the presence of negative relationships. We studied 151 student project teams, and found that teams of mostly women performed better than teams of mostly men, when negative relationships existed among team members. We discuss the implications of these findings for research and practice.

    Geographies of food: ‘Afters’

    In: Progress in Human Geography, SAGE Publications, Vol. 35, No. 1 ( 2011-02), p. 104-120
    Abstract: This third and final ‘Geographies of food’ review is based on an online blog conversation provoked by the first and second reviews in the series (Cook et al., 2006; 2008a). Authors of the work featured in these reviews — plus others whose work was not but should have been featured — were invited to respond to them, to talk about their own and other people’s work, and to enter into conversations about — and in the process review — other/new work within and beyond what could be called ‘food geographies’. These conversations were coded, edited, arranged, discussed and rearranged to produce a fragmentary, multi-authored text aiming to convey the rich and multi-stranded content, breadth and character of ongoing food studies research within and beyond geography.

    Internet-delivered cognitive behavioural therapy for depression: A feasibility open trial for older adults

    Abstract: Depression is an important health issue amongst older adults. Internet-delivered cognitive behaviour therapy (iCBT) may help to reduce barriers and improve access to treatment, but few studies have examined its use with older adults. The present study evaluated the efficacy, acceptability and feasibility of a brief iCBT program, the Managing Your Mood Program, to treat depression amongst adults aged 60 years and older. Method: Using an open trial design, 20 participants with elevated symptoms of depression (Patient Health Questionnaire 9-item (PHQ-9) total scores ≥ 10) received access to five educational lessons and homework summaries, additional resources, a moderated discussion forum and weekly telephone or email contact from a clinical psychologist. Eighty percent of the sample met diagnostic criteria for a major depressive episode at pre-treatment. Results: Completion rates and response rates were high, with 16/20 participants completing the five lessons within the 8 weeks, and post-treatment and 3-month follow-up data being collected from 17/20 participants. Participants improved significantly on the PHQ-9 and Geriatric Depression Scale (GDS), with large within-group effect sizes (Cohen’s d) at follow-up of 1.41 and 2.04, respectively. The clinician spent a mean time of 73.75 minutes (SD = 36.10 minutes) contacting participants within the trial and the program was rated as highly acceptable by participants. Conclusions: The results are encouraging and support the potential value of iCBT in the treatment of depressive symptoms amongst older adults.

    Sport Participation and Subjective Outcomes of Health in Middle-Aged Men: A Scoping Review
    SAGE Publications ; 2022
    In:  American Journal of Men's Health Vol. 16, No. 2 ( 2022-03), p. 155798832210844-

    Abstract: Although sport participation is intrinsically motivating and improves the physical health of middle-aged men, its influence on subjective health measures, such as health-related quality of life, self-rated health, or well-being is unclear. The purpose of this scoping review was to describe the existing literature that has assessed male sport participants and their subjective health. MEDLINE, Embase, Emcare, PsycInfo, SPORTDiscus, Cochrane Library, and Web of Science were searched, and reference lists of included studies were pearled. Included were original peer-reviewed studies reporting a marker of subjective health in males, 35 to 54 years (average), who participated in sport. The search identified 21 eligible articles, 18 quantitative, 2 mixed-methods, and 1 qualitative, from 13 different countries. Eighteen studies were cross-sectional. A broad range of outcomes were assessed, with the most common being quality of life/health-related quality of life ( n = 6) and self-rated health ( n = 6). Most studies assessing quality of life, health-related quality of life, or self-rated health demonstrated a positive association with sport participation, while sport participation was not related to measures of life satisfaction, flourishing, happiness or global well-being; however, limited studies examined these latter outcomes. Sport participation appears to be related to better select subjective health outcomes in middle-aged men. However, most available data are cross-sectional and thus causation cannot be determined. Randomized intervention trials are required to determine whether sport participation improves the subjective health of middle-aged men. Open Science Framework registration: https://osf.io/zypds

    The European Network of Centres for Pharmacoepidemiology and Pharmacovigilance: application to diabetes and vascular disease
    SAGE Publications ; 2011
    In:  The British Journal of Diabetes & Vascular Disease Vol. 11, No. 6 ( 2011-11), p. 304-307

    Abstract: The European Network of Centres for Pharmacoepidemiology and Pharmacovigilance (ENCePP) is an initiative led by the European Medicines Agency (EMA) aimed at further strengthening the post-authorisation monitoring of medicinal products in Europe by facilitating the undertaking of multi-centre, independent, studies focusing on safety and on benefit/risk. A key objective of ENCePP is to provide a unique point of access for all involved stakeholders, including industry or regulatory authorities, who are seeking collaboration for the commissioning or the performance of post-authorisation studies. The 2010 EMA regulatory action relating to rosiglitazone included a pharmacoepidemiological drug utilisation study to evaluate the benefit–risk profile in a real-life setting and has also led to the commissioning of an ENCePP study to evaluate the impact of risk-minimisation activities. ENCePP seeks to improve the European Union capacity to conduct such studies and thus support decision making. Application of the ENCePP study concept will result in an increase in trust in medicines and their use. In addition, the ENCePP register of studies will serve as a resource to allow for ready access to study protocols and results, thereby ensuring transparency.
